Which of the following is an example of a displacement reaction?
A2Mg + O₂ → 2MgO
BH₂SO₄ → SO₃ + H₂O
CCuSO₄ + Zn → ZnSO₄ + Cu
DNaOH + HCl → NaCl + H₂O
Step-by-Step Solution
Step 1: Understand displacement reaction
Displacement reaction involves one element replacing another in a compound.
Step 2: Analyze options
Zn displaces Cu from copper sulfate forming zinc sulfate and copper, which is a displacement reaction. Other options are combination, decomposition, or neutralization.
Final Answer:
CuSO₄ + Zn → ZnSO₄ + Cu → Option C
Quick Check:
Displacement reaction = element replaces another ✅
Quick Trick:Look for element replacing another in compound.
Common Mistakes:
MISTAKES
Confusing displacement with combination or neutralization.
